Comparison of external authentication mechanisms for WebSEAL

This article compares the two supported mechanisms for providing custom authentication services within IBM Tivoli Access Manager for e-business (TAMeB) WebSEAL, C and HTTP, and identifies key differences between them. These key differences are used to identify sets of requirements where one approach is more suitable than the other. A reader can then use these differences to determine which approach to use for their custom authentication processing.
